Abstract

Disclosed herein are methods, systems, and non-transitory computer-readable storage media for conference call session migration. The conference call session migration includes automatically configuring and establishing a target conference call session during a source conference call session; automatically converting session state and session history from a source format of the source conference call session to a target format of the target conference call session, and automatically connecting per-user clients to the target conference call session. For example, in response to a request from a session manger, the participants on the source conference call session are added to the target conference call session in order to add new media or other conferencing capabilities subject to network and server capabilities, user devices, user conferencing software, user location, user preferences, and policies.

Claims

1. A method of conference call session migration, the method comprising a data processor executing computer instructions stored on a non-transitory computer readable storage medium to perform the steps of:

(a) automatically configuring and establishing a target conference call session during a source conference call session;

(b) automatically converting session state and session history from a source format of the source conference call session to a target format of the target conference call session; and

(c) automatically connecting per-user clients to the target conference call session.

2. The method as claimed in claim 1, wherein the data processor is in a conference control server, and the method further includes the conference control server controlling the source conference call session, and while the conference control server is controlling the source conference call session, the conference control server receiving a request for conference call session migration from a session manager of the source conference call session, and then performing the steps (a), (b), and (c) in response to the conference control server receiving the request for session migration from the session manager of the source conference call session.

3. The method as claimed in claim 1, wherein the step (a) of automatically configuring and establishing the target conference call session during the source conference call session includes:

identifying, reserving, and allocating new server resources and new network resources for the target conference call session; and

selecting and configuring user resources and user devices for the target conference call session based on user preferences, user location, user device availability, and policies; and

performing end-to-end mutual authentication and establishment of connections between network endpoints and client software.

4. The method as claimed in claim 1, which further includes the data processor executing computer instructions stored on the non-transitory computer readable storage medium to automatically release source conference call session resources that are no longer needed due to the initiation of the target conference call session.

5. The method as claimed in claim 1, which further includes the data processor executing computer instructions stored on the non-transitory computer readable storage medium to automatically terminate the source conference call session upon establishment of the target conference call session, and to free resources used only by the source conference call session.

6. The method as claimed in claim 1, which further includes the data processor executing computer instructions stored on the non-transitory computer readable storage medium to automatically terminate services of the source conference call session that become redundant upon establishment of the target conference call session, and continuing the source conference call session concurrently with the target conference call session after establishment of the target conference call session.

7. A system for conference call session migration, the system comprising a data processor coupled to a non-transitory computer readable storage medium storing computer instructions that when executed by the data processor perform the steps of:

(a) automatically configuring and establishing a target conference call session during a source conference call session;

(b) automatically converting session state and session history from a source format of the source conference call session to a target format of the target conference call session; and

(c) automatically connecting per-user clients to the target conference call session.

8. The system as claimed in claim 7, further including a conference control server containing the data processor and the non-transitory computer readable storage medium, and wherein the computer instructions, when executed by the data processor, further control the source conference call session, and while controlling the source conference call session, perform the steps (a), (b), and (c) in response to the conference control server receiving a request for session migration from a session manager of the source conference call session.

9. The system as claimed in claim 7, wherein the step (a) of automatically configuring and establishing the target conference call session during the source conference call session includes:

identifying, reserving, and allocating new server resources and new network resources for the target conference call session; and

selecting and configuring user resources and user devices for the target conference call session based on user preferences, user location, user device availability, and policies; and

performing end-to-end mutual authentication and establishment of connections between network endpoints and client software.

10. The system as claimed in claim 7, wherein the computer instructions, when executed by the data processor, further perform the step of automatically releasing source conference call session resources that are no longer needed due to the initiation of the target conference call session.

11. The system as claimed in claim 7, wherein the computer instructions, when executed by the data processor, further perform the steps of automatically terminating the source conference call session upon establishment of the target conference call session, and freeing resources used only by the source conference call session.

12. The system as claimed in claim 7, wherein the computer instructions, when executed by the data processor, further perform the steps of automatically terminating services of the source conference call session that become redundant upon establishment of the target conference call session, and continuing the source conference call session concurrently with the target conference call session after establishment of the target conference call session.

13. The system as claimed in claim 7, further comprising a server containing the data processor and the non-transitory computer readable storage medium, the server further comprising data storage containing a client database and a policy database, the client database storing user preferences and information about user devices and conferencing software, and the policy database storing policies for selecting and configuring the user devices and conferencing software for the target conference call session based upon the user preferences and information about the user devices and conferencing software in the user database.

14. The system as claimed in claim 7, further comprising a first server containing the data processor and the non-transitory computer readable storage medium, the non-transitory computer readable storage medium containing a source conference application program, and the first server including data storage storing source conference reservations, source session state including participants and media of the source conference call session, and source history including a recording of the source conference call session, and the system further comprising a second server containing a target conference application program and data storage storing target conference reservations, target session state including participants and media of the target conference call session, and target history including a recording of the target conference call session.

15. A non-transitory computer-readable storage medium storing computer instructions that, when executed by a data processor, perform conference call session migration by the steps of:

(a) automatically configuring and establishing a target conference call session during a source conference call session;

(b) automatically converting session state and session history from a source format of the source conference call session to a target format of the target conference call session; and

(c) automatically connecting per-user clients to the target conference call session.

16. The non-transitory computer-readable storage medium as claimed in claim 15, wherein steps (a), (b), and (c) are performed in response to a conference control server receiving a request for session migration from a session manager of the source conference call session.

17. The non-transitory computer-readable storage medium as claimed in claim 15, wherein the step (a) of automatically configuring and establishing the target conference call session during the source conference call session includes:

identifying, reserving, and allocating new server resources and new network resources for the target conference call session; and

selecting and configuring user resources and user devices for the target conference call session based on user preferences, user location, user device availability, and policies; and
